HOT-METAL CAR.

Application led May 13, 1920. Serial No. 381,057.

To all 'whom t may concern.'

Be it known that we, ALFRED C. NELSON and EDGAR J. REILLY, both citizensof the United States, residing respectively at Lakewood, county ofCuyahoga, and State of Ohio, and Youngstown. county of Mahoning, andState of Ohio. have invented a new and useful Improvement in Hot-MetalCars, of which the following is a full, clear, and exact description.

The present invention relates broadly to cars or carriers for moltenmetal or other materials, and more particularly to cars intended for hotmetal, cinders and the like.

An important object of the present invention is to provide a compactlydesigned car having both increased capacity and strength.

Another object of the present invention is to provide a car of thecharacter described having a mounting from which it is readilyremovable.

Still another object of the invention is to provide a support comprisinga pair of spaced trucks connected by a longitudinally extending centersill or brace whereby the trucks are maintained in predetermined spacedposition when the container is removed therefrom.

A further object of the invention is to provide the trucks withanti-friction bearings on which the container may be rotated and whichare adapted to prevent endwise movement of the container duringrotation.

The foregoing and other objects. together with their attendantadvantages, will be apparent as the invention becomes better understoodhy reference to the accompanying specification and drawings forming apart thereof, it being premised that changes may be made in the variousdetails and the manner of operation within the scope of the appendedclaims without departing from the spirit of the invention.

Figure 1 is a side elevation of a portion of our improved hot metal car:

Figure 2 is a plan view partly broken away of one form of the container;

Figure 3 is an end view of the construction illustrated in Figure l;

Figure 4 is an end view, partly broken away, of the opposite end of thehot metal oar;

Figure 5 is a cross sectional View through the form of the carillustrated in Figure 1; and

Figure 6 is a similar View through a slightly modified form of car.

This invention provides aV carrier of large capacity, for distributinghot metal from a blast furnace to the required point of dispositionabout steel works or foundries, such as mixers, pig casting machines,moulds, etc.

It isy desirable that a carrier for use in transporting hot metal,cinders and the like, be constructed as compactly as possible withoutinterfering with the strength or capacity thereof. As these carriers arefrequently adapted for receiving and transporting as high asseventy-tive or more tons of material at a time, the importance of thesefeatures will be apparent. At the same time, it is desirable to providea simple mounting for the container which may permit rotation thereofwhile functioning as a supplemental tie between the spaced trucks. andprevent-4 ing accidental longitudinal movement of the container.

Not only does the container rotate on the trucks as described. but it isof suoli design that it can be equipped with lifting lugs so it can beraised while full of metal and lifted to any desirable receivingreceptacle, such as a mixer, etc., without requiring any disconnectionof any parts. The container, when emptied, may then be returned to itsproper position on the car body without requiring any connection ofparts.

ve have found that all of these desirable features may be produced byconstructing a container which is oval or elliptical in longitudinalsection as described hereinafter.

Referring more particularly to the drawings. there is illustrated inFigure 1 a hot metal car construction comprising spaced trucks 1 and 2which may be of any desired construction. Extending rearwardl from eachof the truck frames is a projection 3 to which are secured the oppositeends of the longitudinally extending center sill or brace 4. This centersill serves to effectively tie the trucks together to always maintainthe same in proper spaced relation for the reception of a hot metalcontainer. At the same time, by reason of its central location, thissill is entirely out ofthe way and permits the operation of the hotmetal car as desired.

The container in its preferred embodiment comprises a main body portion5 whichl may consist of a suitable refractory lining 6 and an outerenclosing metal shell or casing 7. In order to provide a constructionhaving a maximum strength and capacity, the body of the container may beformed either as an ovoid or ellipsoid of revolution. Such a shapeprovides a container which is curved or arched in every section, therebyinsuring a maximum strength. This shape also facilitates discharging thecontainer as the contents thereof readily follow the contour of therefractory lining.

Secured to each end of the container 5 is a trunnion 8. These trunnionsare each provided with a concave surface 9 adapted to receive the endsof the container 5 and partially embrace the same. If desired, theentire structure may be reinforced by employing metallic braces 10eXtendin between the trunnions. The outer en of each of the trunnionsare preferably cylindrical in shape and are formed with an enlargedcylindrical flange 11. These flanges are adapted to co-operate bygravity with anti-friction bearings 12, suitably mounted on each of thetrucks 1 and 2 as clearly shown in Figures 1 and 4. aoh of the bearingsma comprise a series of flanged rollers, the anges on the rollersco-operating with the enlargement 11 on the trunnions 8 for preventinglongitudinal movement of the container and at the same time functioningas a. tie between the trucks supplementing the action of the center sill4.

In the form of container illustrated in the first five figures of thedrawings, there is provided an oval' discharge opening 13 extendingsubstantially the entire width of the container and provided wit-hoppositely disposed pouring lips 14. For rotating the container topermit discharge of material over either of the pouring lips, there maybe provided a motor 15, on the truck 1, for driving any suitable type ofreduction gearing 16 intermediate the motor and container. Thisreduction gearing may mesh with a large gear 17 secured to one of thetran= nions 8, the point of engagement with the gear 17 being below theaxis of rotation of the container, as clearly shown in Figure 3.

In some instances it has been found desirable to construct the containerwith a plurality of independent pouring openings 18, as shown in Figure6. In such cases, each of the pouring openings will be provided with asuitable lip 19 over which the material may be discharged.

Due to the particular location of the center sill 4, and the sha e ofthe container 5, the container may e rotated from its upright positionthroughout more than 9()O in elther direction, thereby permitting acomplete discharge of the contents of the container. This dumpingposition is illustrated in dotted lines in Figure 3 of the drawings. Ifside sills were employed for connecting the trucks, such a dumpingoperation could not be obtained and if the connecting sills are entirelyeliminated the trucks will be capable of independent relative movementwhen the container is removed therefrom, thereby preventing expeditiousreplacing of the container in the anti-friction bearings provided.

One end of the. motor shaft may be provided with a suitable brake drum15' by means of which the container can be held in upright positionduring transportation thereof, or by means of which the rotation of thecontainer may be checked.

The advantages of the present.invention arise from the oval orelliptical shape of the container which permits ready mounting of thesame by the use of trunnions as described.

Further advantages of the invention arise from the use of a center sillfor tying the trucks in predetermined `spaced relation.

Still further advantages arise from the construction permitting rotationof the container andremoval thereof from the supporting trucks withoutnecessitating anv manual operations of connecting and disconnecting.
